With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.768-66-1,2,2,6,6-Tetramethylpiperidine,as a common compound, the synthetic route is as follows.,768-66-1
[REFERENCE EXAMPLE]The procedures for synthesizing 2-(2,2,6,6-tetramethylpiperidinylmethyl)phenylboronic acid used as a catalyst (hereinafter, written as the catalyst C) will be described below. This compound is a known compound. [0023] First, a flask was loaded with 2-bromobenzyl bromide (10 mmol), potassium carbonate (22 mmol), potassium iodide (11 mmol), 3-pentanone (20 mL) and 2,2,6,6-tetramethylpiperidine (22 mmol). The mixture was heated under reflux for 2 days. After being allowed to cool to room temperature, the mixture was filtered to remove the insolubles. The filtrate was washed with water 2 times, and the aqueous phases were each extracted with chloroform. The organic phases were combined together, dried with sodium sulfate, and concentrated under reduced pressure. The resultant crude product was purified by column chromatography (NH silica gel, hexane), thereby obtaining the target amine compound, namely, 1-bromo-2-(2,2,6,6-tetramethylpiperidinylmethyl)benzene in 92% yield.
768-66-1 2,2,6,6-Tetramethylpiperidine 13035, apiperidines compound, is more and more widely used in various fields.
